how can I create a struct with row vectors

Question

0 个投票

I create a struct:

gt_tracks(num_gt_tracks) = struct('Position', [], 'Velocity', []);
    for j = 1:num_gt_tracks
        gt_tracks(j).Position = [gt(j,2:3), 0];
        gt_tracks(j).Velocity = zeros(3,1);
    end

but in this code:

OSPA(t) = OSPAMetric(tracks, gt_tracks);

OSPA requires 'Position' and 'Velocity' fields must be row vectors.

so what should i do?

It is quite straightforward to create row vector components for a Structure array. E.g.:

t=linspace(0,13, 131);

GT.Pos = randi([-13, 13],1, 131);

GT.Vel = 2.5*t-5;
